Embodiment Construction

[0070] The present invention is applied to a transmission power amplifier. The transmission power amplifier is used to control the power of a signal to be transmitted. The main feature of the present invention is to generate a nonlinear power control curve in the power variation region to control the power variation of the signal. , so as to reduce power consumption. The power changing region has at least one transmit power value K and can be divided into a ramp-up region, a ramp-down region and an intermediate ramp region. The generation of the power control curve of the present invention mainly generates the original curve and determines the minimum power value H according to the transmission power value K. The original curve is horizontally divided into an original curve left section FL and an original curve right section FR. Then according to the transmission power value K and the lowest power value H, the left segment ratio SL and the right segment ratio SR are determine...

Abstract

A control method and a device for a power-transmission amplifier is used to generate a power control curve in a power variance region to control the power variance of signals to be transmitted when transmitting data in the continuous or adjacent first time slot and a second time slot, which have different modulation kinds with K1 of the first transmission value and K2 of the second transmission value separately. The concave intermittent control curve can control the power intensity of the amplifier to transfer from K1 to K2 to reduce the intensity of the power transmitted in the protected regions.

Description

technical field [0001] The invention relates to a control method and device of a transmission power amplifier, in particular to a control method and device of a transmission power amplifier applied to a wireless communication system. Background technique [0002] The wireless communication system transmits the data to the remote through the atmosphere, and strengthens the power of the signal through the transmission power amplifier (TX Power Amplifier, TX PA) to prevent the signal from attenuating into unrecognizable noise before reaching the remote destination. Generally speaking, before transmitting a valid signal, the power of the TX PA needs to be increased to the power level to be sent. This process of increasing the power is called ramp-up (RampUp); after transmitting the valid signal, the power of the TX PA needs to be Back to the lowest level, the process of reducing the power is called ramp down (Ramp Down). [0003] In an existing Time Division Multiple Access (TD...
